What is your favourite pop/soda drink?

I alternate between a bunch, most often:

any black cherry (usually Boylan's is easiest to find at home)
Coke & Vanilla Coke
cream soda (no strong preference but we usually end up with Stewart's)
Dr. Pepper
egg cream (it's a NY drink--no eggs or cream in it oddly enough)
Mountain Dew
root beer (same as with cream soda)
